Mike Grover is a security researcher, InfoSec expert, and the creator of the infamous O.MG Cable. He gained prominence in 2019 when he showcased his malicious USB cable prototype at DEF CON, capable of recording keystrokes and executing remote commands. Grover's O.MG Cable looks identical to a regular charging cable, but contains a tiny implant that creates a Wi-Fi hotspot, allowing attackers to access the connected device from up to 300 feet away.

Since its inception, Grover has refined the O.MG Cable design, making it indistinguishable from normal USB cables and expanding its capabilities. The latest iteration includes features such as geofencing, self-destruct mechanisms, and support for various connector types including Lightning and USB-C. Grover's work aims to raise awareness about hardware security risks while providing tools for red teams and security researchers to test and improve organizational defenses.
